IMPROVEMENT IN ROOFING-TILES.

Specification forming part of Letters Patent No. 160,445, dated March 2, 1875 g application filed January 13, 1875.

To all whom it may concern:

Be it known that I, JOHN M. LEWIS, of New Castle, in the county of Coshocton and State of Ohio, have invented certain new and useful Improvements in Roofing-Tile; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings and to the let-ters ot' reference marked thereon, which forni a part of this specification.

My invention relates to improvements in rooting-tiles. It consists in the construction of the tiles in the manner hereinafter fully `described, and specifically pointed out in the claim.

In the drawings, Figure 1 is a plan View of a portion of a roof constructed from tiles made in my improved form. Fig. 2 is a sectional view on the line fr x, and Figs. 3 and 4 are views of opposite sides of a tile of each series.

A and B are the two tiles. The tile A com-v poses what I, by preference, denominate the lirst or under series, and B the second or upper series. In the first series the upper and under sides of a tile are shown in Fig. 3, A being the under side; and the same with reference to the second series is shown in Fig. 4, Bl being the under side.

In tile A,on the upper side, and at suitable distance from the edge, is cut the half-depth ot' said tile, the longitudinal grooves a forming the tongues al. Across the upper end of the tile, and extending between and ush with the grooves a, is raised the shoulder a2, having a thickness equal to halt the thickness ot tile B, and on the central portion of this shoulder is formed the tongue or rib a3. c4 are two stops or keys placed in grooves a, opposite, or nearly opposite, the ends of the tongue a3. a5 are a number of water-channels formed on the top of the tile, to facilitate the collection and carrying away the water that may fall thereon. The under side of tile A, as shown at A', Fig. 3, is made smooth,

except that I form the groove a6 across the lower end, into which the tongue or rib e3 on the tile in the course next below lits.

The second or upper series of tiles B are inade very similar to series A, the similarity of construction appearing reversely, or on opposite sides and ends. rIhe upper side is provided with the cross-groove b at its upper end, and is furnished with the water-channels b1. The under side is provided, at its lower end, with the shoulder b2 and tongue b3, and with the grooves and tongues b4 b5, corresponding to grooves and tongues a al, with which they interlock. b are two notches cut across the tongues b5 to lit over and lock on the keys a4.

In laying the tiles to forni the roof I commence at, and lay a course or portion thereof along, the eave. The tiles A are the first placed. Each two contiguous tiles are placed apart such distance that when the tileB is placed in position the tongues and grooves a a and b4 b5 will interlock, and the intervening space be closed. The tile B being putin position and interlocked, as above stated, the notches b will lock over the keys a, and et'- fectually prevent the tile from slipping downward, and thus obviate the necessity of nailing every tile.

It will be seen that were the irst course along the eave lirmly secured the entire roof could be laid without the use of any nails. In the construction of the tiles I form suitable nail-holes in the grooves c, so that, when desired, such tiles may be nailed as may be deemed best.

In continuing the laying of the roof, the tongues and grooves across the lower under side of each tile lit over and on the corresponding construction on the upper end and side of the tile in the course next below, each tile joining upon the one of its own series in the lower course. The shoulders a2 b2 close down tight against its connecting tile, and completely close the space between the two courses.

Ihus it will be seen that a close-tting joint is formed, as shown in Fig. 2, through which no snow or rain can be driven by the Wind, and that a firm, substantial roof is oonarranged to join together in the manner `etnd strueted. for the purpose specified.

Having described my invention, what I In testimony that I claim the foregoing as claim, and desire to secure by Letters Patmy own I hereto affix my signature in present, isence of two Witnesses.
